During the (northern) winter of 2025–2026, the Blender development team prioritized improving stability and overall quality.

Blender's platform is a leading open-source 3D creation suite, offering insights into 3D modeling, animation, and rendering. Through tutorials, documentation, and community forums, Blender provides insights into creating stunning visual effects, animations, and interactive experiences. Artists and designers can learn about Blender's powerful features, such as sculpting tools, rigging, and physics simulations, to bring their creative visions to life.

Blender's development team completed a focused quality initiative during winter 2025-2026, fixing over 350 reported bugs across 14 modules. Beyond bug fixes, developers tackled technical debt, modernized C++ code, improved performance in animation and rendering systems, added automated tests across multiple modules, and reduced untriaged reports from 90+ to ~20. Major work included removing legacy animation code, refactoring the compositor for reusable node trees, transitioning mesh attributes to a new storage format, and cleaning up the Video Sequence Editor codebase.
